Description

Overview

GE IS200EDCFG1A is an Exciter DC Feedback Board in the Mark Vi series. Installed near the SCR (thyristor) rectifier bridge, it primarily detects the generator's excitation current and voltage and transmits this data via a fiber optic link to the Exciter Interface Slave Board (EISB) in the control cabinet.

Product positioning: The "parameter acquisition and feedback center" of the excitation system, connecting the SCR bridge and the EISB control board

🚀Function & Features

Field Voltage Feedback: The IS200EDCFG1A acquires voltage signals by monitoring the negative terminal of the rectifier bridge and the positive terminal of the current shunt. The board offers seven selectable jumper settings.

Field Current Feedback: The IS200EDCFG1A measures the field current through a DC shunt, generating a low-level signal (maximum 500mV).

Signal Processing Technology: The IS200EDCFG1A uses voltage-controlled oscillator (VCO) technology to convert analog voltage and current signals into frequency signals for transmission via optical fiber.
